Rehabilitation of Cedar Lane Bridge over Rock Creek. Montgomery County, Maryland.

Maryland Base Relocation and Closure work was being completed at the National Institutes of Health and the National Navy Medical Center which impacted the schedule for this project. Due to a compressed construction schedule, the use of precast concrete allowed the new bridge to be erected in nine calendar days and the proposed bridge erection to be completed in twenty-one calendar days from the road closure. The other benefits to precast concrete include: lower maintenance costs for the life of the bridge; the bridges strength will increase over time; and variables, such as weather and humidity, are eliminated because the precast concrete is produced in a factory.
